CROSS REFERENCE TO RELATED APPLICATION

This patent application claims the benefit and priority of Chinese Patent Application No. 202122472958.9 filed on Oct. 14, 2021, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.

TECHNICAL FIELD

The present disclosure relates to the technical field of fabrics, and in particular relates to a cotton knitted fabric with antibacterial, deodorizing and anti-mold functions.

BACKGROUND ART

With the development of economy and society and the improvement of people's living standards, the comfort and functionality of clothing fabric are attracting more and more attention.

Cotton fabric is favored by consumers due to good warmth retention property and breathability. However, under a condition of proper temperature and humidity, cotton fabric is prone to breeding bacteria and fungi after moisture absorption, so as to become a good parasite for microorganisms to survive and reproduce. The bred bacteria and fungi are harmful to the human body, causing the human to be infected with skin diseases and making the fabric stained with sweat and human body secretions to generate odor; and also, the skin diseases and the odor may in turn pollute the cotton fabric to cause damage, thus adversely affecting the life and quality of the cotton fabric.

In the prior art, in order to avoid above issues of the cotton fabric, non-cotton fabrics are usually used instead. For example, Chinese Patent Publication CN208121303U discloses an antibacterial knitted fabric. A face side of the antibacterial knitted fabric is woven from hydrophilic yarns, the hydrophilic yarns are polyester filament yarns subjected to hydrophilic treatment. A back side of the antibacterial knitted fabric is woven from antibacterial yarns, and the antibacterial yarns are blended yarns of antibacterial fibers and profiled polyester fibers. Moreover, according to this scheme, the antibacterial knitted fabric forms a dual-sided structure through tuck stitch, the face side of the antibacterial knitted fabric is flat and smooth, and the back side of the antibacterial knitted fabric is provided with rhombus-shaped abbatre. The minimum patterns on the back side each contains six courses and three wales, and the minimum patterns of the back side of the antibacterial knitted fabric each are six feeds as a cycle. Therefore, on one hand, as the scheme does not employ the cotton fabric, the advantages of good warmth retention property and breathability of the cotton fabric are lost although some issues caused by the moisture absorption of the cotton fabric are avoided, on the other hand, the two sides in the scheme are different in material and structure, resulting in complex process and limited use.

In addition, Chinese Patent Publication CN208362605U discloses a rib fabric. A face side of the rib fabric is formed by face pattern repeats, and a back side of the rib fabric is formed by back patter repeats. The face pattern repeat and the back pattern repeat are both composed of four wales and four courses. And in a cam arrangement diagram, a draw-down cam, a tuck cam and a non-knitting cam in the face pattern repeats and a draw-down cam, a tuck cam and a non-knitting cam in the back pattern repeats are symmetrically arranged, that is, a structure with the face side and the back side being symmetrical is adopted in this scheme. Thus the face side and the back side need to be distinguished during the application, leading to a certain limitation. And moreover, materials with the antibacterial and deodorizing functions are not adopted in this scheme, and it is unclear whether the antibacterial and deodorizing functions can be achieved or not.
